Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking

Laser &Photonics Reviews, EarlyView.
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Generation of Optical Quasiparticles with Spin–Orbit Conversion in a Single Q‐Plate

Laser &Photonics Reviews, EarlyView.
Spin‐Orbit conversion approach with a q‐plate for generating optical quasiparticles. ABSTRACT In this work, we detail a novel approach which can be used for the generation of optical quasiparticles. This process leverages both spin‐orbit conversion control with wavelength de‐tuning in a commercially available q‐plate.

Topological Photonic Devices and Circuits at Terahertz Frequencies

Laser &Photonics Reviews, EarlyView.
This review examines how 3D topological insulators and emerging topological photonic phases enable robust, low‐loss and defect‐immune terahertz devices. Fundamental properties, device implementations and topological transport mechanisms are surveyed, revealing new opportunities for reconfigurable, high‐performance THz components and scalable ...

Enhancing Lipidomics With High‐Resolution Ion Mobility‐Mass Spectrometry

PROTEOMICS, EarlyView.
ABSTRACT Lipids, indispensable yet structurally intricate biomolecules, serve as critical regulators of cellular function and disease progression. Conventional lipidomics, constrained by limited resolution for isomeric and low‐abundance species, has been transformed by ion mobility‐mass spectrometry (IM‐MS).
